Przedstawiono podstawowe informacje z zakresu modelowania systemów technicznych. Zaprezentowano możliwość modelowania złożonego systemu technicznego za pomocą modelu matematycznego – sieci Petriego, analizując ich praktyczną i dydaktyczną użyteczność.
Presently discrete-event dynamic systems represent a significant group of varied systems e.g. computer networks, manufacturing systems, communication systems, database systems etc. An important class of discrete-event systems are automated storage and retrieval systems (AS/RS). These systems are equipped by robots and other automation technology. The article deals with Hierarchical Coloured Petri...
A generalised stochastic Petri net (GSPN) model is presented for the modelling and analysis of a burst switching integrated voice/data service (IV/DS). Analyses are performed in terms of the data delay and voice cutoff fraction of the service node. To properly model the network, the concept of an 'overflow' arc is introduced to the GSPN. Based on the analysis, the author presents a modification to...
